This invention relates to improvements in hair curling clamps and. rods,more particularly to such devices employed in what is known as theCroquignole waving of hair wherein the hair strands are wound on a rodand held by a clamp preliminary to the application of a heating mediumthereto.

It is among the objects of the invention to provide improved means forlocking the curling rod to the protector clamps when winding of the hairthereon has been completed.

A further object of the invention is the provision of a curling rodhaving an external ratchet at one end thereof and a spring biasing meansat the opposite end whereby the ratchet teeth coact with a rigid pawlprovided on the protector clamp.

Still a further object of the invention is the provision of a curler rodand protector clamp in combination which shall be of durable andeconomical construction and which shall be free from clogging by foreignparticles.

These and other objects of the invention will become more apparent froma description of the accompanying drawing constituting a part hereof inwhich like reference characters designate like parts and in which:

Fig. 1 is a top plan view of a protector clamp in the open position;

Fig. 2 a top plan View of the assembled protector clamp and curler rodembodying the principles of this invention;

Fig. 3 a vertical cross-sectional view of the curler rod takenlongitudinally along the lines 33, Fig. 2;

Fig. 4 a transverse cross-sectional view of the clamp and rod takenalong the line 44, Fig. 3; and

Fig. 5 an end elevational view of the curler rod.

With reference to the several figures of the drawing, the structurestherein illustrated comprise a clamp constituted by the hinged jaws land 2 pivoted at 3 and provided with a lock lever 4 that constitutes nopart of the present invention, the clamp in its closed position havinglever 4 lying adjacent one side as shown in Fig. 2.

The numeral 5 generally designates the curling rod which is adapted tobe mounted on end brackets 6 and I of the protector clamp, the rod beingso mounted by journals 8 and 9.

Both ends of the rod 5 are recessed at H] and. II, the recess lll beingof square shape to receive a winding key by which suitable tension isapplied to the hair strands after they are wound on the rod. The recessI I which is counterbored as shown is adapted to receive the journal pin8 and a coil spring l2, the latter abutting one wall of the recess H andthe shoulder on the journal pin 8, whereby the latter is normally biasedoutwardly from the curling rod l l to seal the recess H and preventtreating fluid and grit or hair from clogging the recessand workingparts. The end of the rod opposite the resiliently mounted journal pin 8is provided with a ratchet toothed face l3 which interacts with astationary pawl 14 clearly shown in Fig. 1 of the drawing, the biasingpin 8 forcing the curler rod 5 against the pawl [4 with teeth l3 at alltimes in' engagement therewith.

In the operation of the above described curler rod and protector clamp,the latter is clamped with its faces engaging strands of the hair thathave been separated to be curled, the clamp being placed adjacent theskull with a protecting felt therebeneath. The ends of the separatedhair strands are then wound around the curler rod which is engaged atits ends by the operator who continues turning the rod to wind the hairwhile bringing the rod nearer the clamp and when it is all wound the rodis snapped in the brackets 6 and I of the protector clamp as shown inFigs. 2 to 4 of the drawing. The key for winding the rod to apply thenecessary tension to the hair strands is then inserted in the recess [0and the rod is wound while in the protector clamp journals to impose thedesired tension upon the hair strands, and the pawl M will hold the rod5 in any angular position against the tension of the hair strands.Suitable heating means is then applied either by the so-called heatlesspad method or electrical resistance or steam heating methods or in anyother suitable manner to permanize the strain imposed upon the hair bythe curling action.

It is evident from the foregoing description of this invention that theprovision of the ratchet teeth on the end face of the rod with thespring biased journal pin at the oposite ends is a positive means ofapplying and maintaining the necessary tension on the hair strands and aconvenient means of winding the hair after it has been curled on the rodelement.

The accessibility of the teeth permits keeping them clear from foreignmatter so as to avoid interference with their proper function as inother types of ratchet devices heretofore in use, particularly thoseobtained with the curler rod. The spring biasing means employed providesa rugged and inexpensive construction which is not subjected to failurethrough breakage or tortion.

Although one embodiment of the invention has been herein illustrated anddescribed, it will be evident to those skilled in the art that variousmodifications may be made in the details of construction withoutdeparting from the principles herein set forth.

I claim:

1. A protector clamp and curler rod having cooperativeratchet elementsat one of the end faces of said-clamp and rod in cooperativeendisgagement and having a spring element disposed
